203 W Mason Avenue presents a rare opportunity to own a reimagined storybook home, where timeless charm meets a comprehensive, design-driven renovation and expansion in one of Alexandria’s most beloved neighborhoods.

Set in coveted Rosemont, the home captures the essence of classic cottage architecture while offering the ease and sophistication of fully updated living. Thoughtfully expanded and rebuilt by Akseizer Residential, the residence reflects a careful balance of craftsmanship, functionality, and elevated design.

A custom high-gloss lacquered mahogany front door creates a striking first impression, opening to interiors defined by rich, dark-stained oak flooring and a natural, flowing layout. The main level unfolds with intuitive connectivity, where the living room, anchored by a fireplace with a Carrara marble hearth and surround, transitions seamlessly into the kitchen and adjacent living spaces, creating an ideal environment for both everyday living and entertaining.

The kitchen serves as a true focal point, pairing custom cabinetry by Akseizer Residential with quartz countertops and an integrated stone sink. A Waterworks unlacquered brass faucet adds warmth and character, while a suite of Bosch appliances, including integrated refrigeration, dishwasher, and microwave, is complemented by a statement Ilve 40-inch dual-fuel range in a limited-edition white finish with brass hardware.

Upstairs, the home offers well-proportioned bedrooms thoughtfully arranged for both comfort and privacy, including a primary suite enhanced by custom built-in cabinetry. Bathrooms throughout reflect a cohesive and timeless palette, featuring white Carrara tile, custom vanities, and Waterworks polished nickel fixtures with frameless glass enclosures. The lower level extends the home’s functionality with additional living space, laundry, storage, and flexibility for a home office, gym, or media area, enhancing the home’s overall livability.

The home’s setting is a defining element of its appeal, thoughtfully conceived to create a seamless dialogue between indoor and outdoor living. A beautifully designed rear terrace and garden extend the interiors with effortless grace, offering an ideal backdrop for both quiet moments and refined entertaining. Tucked discreetly beyond, the detached garage introduces everyday convenience while preserving the property’s architectural integrity, charm, and sense of scale.

Updated HVAC systems, including a new central system and a dedicated Carrier mini-split for the rear addition, ensure comfort and efficiency throughout.

Ideally located near the shops, cafés, and community feel of Del Ray, and just minutes from Old Town Alexandria and commuter routes into Washington, D.C., the home also benefits from close proximity to highly regarded public and private schools, offering both lifestyle, accessibility, and long-term value in equal measure.

A rare opportunity, 203 W Mason Avenue delivers the charm of a storybook cottage with the scale, design, and livability of a fully modern home.
